Red Winter.

Carla Andrews and Daniel Marx, a couple in a rocky relationship, decide to take some alone time in the Colorado mountains. After arriving, they quickly learn that they are far from solitude when Carla witnesses a murder at the hands of two cartel hit men. With the killers stalking them through the bitter cold, Carla must use her survival skills taught to her by her father to ensure she's the predator and not the prey in this bloody fight for survival. —John Prescott
